AERODYNE ENVIRONMENTAL introduced the high-temperature Vacu-Valve®, a low-cost, low-maintenance trickle valve system equipped with a replaceable silicone duck bill sleeve that can operate in temperatures up to 500°F. The Vacu-Valve is available in two designs, the open-construction Platypus and the closed-construction Armadillo. The replaceable sleeves are chemical- and caustic-resistant, as well as abrasive resistant. It is available in both carbon steel and stainless steel.
Both the Platypus and Armadillo are cost-effective solutions to rotary valves for particular applications. These trickle valve systems operate as constant discharge valves for dust collectors, hoppers, cyclones, and other equipment operating under negative pressure. The duck bill designs allow for dispensing dry free-flowing material continuously and, unlike rotary valves, have no moving parts to maintain.
The low-maintenance Vacu-Valve requires no lubrication, controls, or power supply; whereas rotary valves require a power driven motor. The Vacu-Valve is ideal for "keep empty" dust-collection units.
Aerodyne Vacu-Valves are an efficient and economical solution for emptying particulate from dust collectors and baghouses. They offer a range of valves, including: double dump, slide gate, rotary, and knife gate valves.
